In VPOP3 a Mailing List is a list of email addresses which can have messages sent to it by emailing one address. For instance, if you have a list called customers, then you could email all your customers by sending a message to customers@mycompany.com.

A Mailing List is more flexible than a Distribution List. It can do everything a Distribution List can do, and a lot more, but is a bit more complex to configure because of the extra options.
